Need a web friendly version of a picture in SharePoint?

SharePoint automatically creates web friendly version of your pictures within a Picture Library. I’m not talking about SharePoint 2013 Image Rendition, but completely OOTB vanilla SharePoint, and it has been doing it even a few versions back.

So, add a picture to your SharePoint sites, picture library.

Then have a look:

Original Picture:
{SharePoint Site}/{Picture Library Name}/MyNewPicture.png

Web Copy:
{SharePoint Site}/{Picture Library Name}/_w/MyNewPicture_png.jpg

Thumbnail:
{SharePoint Site}/{Picture Library Name}/_t/MyNewPicture_png.jpg
